HORSESHOE-CALK.

Specification of Application filed January 23, 1915.

To all whom it may concern:

Be it known that I, FREDERICK'SOHMIDT, citizen of the United States, residing at Dal ton, in the county of Lackawanna, and State of Pennsylvania, have invented new and usefullmprovements in Horseshoe-Calks, of

shoes and horseshoe calks.

lt'consists, firstin the combination with tageous calks so arranged as to afford a the front and back calks assuming positions,

solid footing for a horse, and so as to assure perpendicular to the pavement or roadway when the horse is in motion, this with a view to enabling the calks to readily pene- .trate snow or ice or a slippery pavement without material Wear of the calks, and, secondin' calks so constructed that they are adapted to be securely socketed in a shoe body without injury to the calks by the ham- ,merfblows, and also adapted to prevent a.

horse slipping sidewise as well as in forward and backward directions and yet are not "liable to be filled with snow or ice.

. Other advantageous characteristics of the invention will be fully understood from the f ings, accompanying and forming port of,

following description and claims when the same are read in connection with the draw-.

this specification, in which:

, Figure 1 is an inverted 'planview of-a horseshoe constructed in accordance with my invention. Fig. 2 is a side elevation of the shoe, with a portion of the shoe body in section. Fig. 3 is a detail vertical section ilustrating the manner in which the shanks of the "calks are socketed in the shoe'body. Fig. {is a detail perspective of a modified calk hereinafter "specifically referred to.

,Referri'ng by numeral to the said drawings, and more particularly to Figs. 1 to 3 thereof:' 1 is theshoe body, and 2-2 arelthecalk's, the'shoe body being formed of wrought iron, andthe calks being made in any'appr'oved manner of steel or any other "hardi inaterial compatible with their purpose; I v

In accordance with my lnvention, the

shoe body is provided with" four (more or less) upwardly-tapered sockets 3 which extend vertically through the body from the By reference to Figs. 1 and 2, it

noticed that the convex sides of the forward I concavo-convex portionsf0f the 'rear calks are inclined downwa dly and rearwardly from the'vertical. Otherwise the calks are identical in constructionandjtherefore' a detailed description the calkshown in Fi 3 will suffice to impart a definiteunderstan ing of all. Thecalk referredto is made in one piece, and comprises 'an' 'up'wardly tapered shank 4;, having, by preference, an uprightifin or feathe r 5 'onjits side, an enlargement (ia'rranged at the lower end of the shank and; at right. angles thereto and having an unders ide,7 also'disposed' at right angles tothe. shank, and the portion 8, of concavo-conyex form in cross-section, carried and depending from the enlargement- 6,; and having a lower *beveled end 9.-

with and to have its efficiency impaired by snow ,or ice. 'It will also "be manifest that the sides of the said portion8 will preclude sidewise or lateralfslippingof the calk on a a slippery pavement, while ,the, front part of. the concave-convex portionwill efiectually' prevent slipping of-the can: forwardly-orrearwardlyi. I would also have it understood at thispoint that by reason of the calks having the concave-convex portions, arranged in inclined positions-from the vertical, as best shown in Fig; 2, the intermediate. partsoffthe lower endsof the calks will firstengage the grounder; pavement when the horse is in motion. This is'advantageous inasmuch as the said intermediate parts of the lower ends will first penetrate theg roaglway or the snowuor' ice' thereon, and infftliat way will assure the"l i orse-gaining a secure fdotfhold withoutunnecessary wear'of the lower ends of the calks. "Itwill further be noticed that by "reason of the inclination- 0f .the concave-convex portions of the calks from the vertical, the calks will rest perpendicular to thepavement'or roadway when the shoe body is inclined with respect to the .cause of this, thecalks arefcertain to be nnbedded in the, sur face of the roadway and will be will not slip idly oversaid surface aswou-ld 110 surface of thefpavementbr roadwayr g -Be arranged perpendicular or at right angles to the shoe body.

Manifestly when the. shanks l equipped occasion demands any one of the calks can with fins bffeathers 5 are driven into the tapered sockets 3 ofthe shoe body, the said fins or feathers Will out ways in the ,walls of the sockets '3 and will thereby effectually prevent the calks turning about their axes in the body; f

An important advantage pecullar to my novel calks resides in the disposition of the undersidcs 7 ofthe enlargements 6 at right I angles to the vertical-centers of the calk shanks. The said arrangement of the undersides 7 is of advantage because when it is desired to drive a Vcalk -into its complementaryisocket in the shoe body a. punch ,can be arranged with its inner end i 'ainst the underside 7 of the enlargement 6 of the v oalk, and hammer blows can be imposed on -the outer end of the punch to drive the calk shank home, or if preferred the blows of a thin hammer head can be imposed directly against the said underside 7. When. this is done it will be observed that breaking down of or any other injury to the sharp ened end 9 of the concavo-oonvex portion 8 of the calk is precluded, which is an important advantage.

W henttheJ shanks of the calks are fully socke'ted'in the shoe body 1, it will be noticed thatithe calkenlargementsfi are spaced. from the underside of the body 1. This is advantageous since it permits ofa wcdging instrument: being driven between the enlargements 6 and the underside of the shoe bodyto withdraw the calk shanks from the soloketsin the body.

The modified calk 2* shown in Fig. 4 is similar in construction to the calks shown in Figs; ljto 3, in all respects with the exeption thatthe concavo-convex portion 8 '01 the modification is made angular instead of curvilinear. It is to be noted however that the-modified calk is possessed of all of the'practical advantages hercinbefofe ascrilicd mole calks illustrated in Figs. 1 to It will be gathered from the foregoing lithat notwithstanding-their practical advaning cheaply produced and are adapted to be expeditiously and easily secured by frictional contact in a shoe body, without'the employment of skilled labor, and that when be as readily removed from the shoe body. There is however, no liability of the calks becoming loose or being lost incidental to the use of the shoe equipped with the calks.

It is obvious that when desired the sockets 3and the shanks 4 may be inclined conform--- ably with the calk portions 8, Without in volving departure from the scope of my claims.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. In a horseshoe, a shoe body, and forward and rear calks fixed to and depending from the body and having lower portions of concave-convex form in cross-sectionterminating in square and beveled lower ends; the convex sides of the forward calksbeing arranged foremost, and the convex sides of the rear calks being arranged rearmost, and the concavo-convexportions of the forward calks being inclined downwardly and forwardly from the vertical, and the concavo-' convex portions of the rearcalks being inclined downwardly and rearwardly from the vertical.

2. As a new article of manufacture, a onepiece horseshoe calk comprising an upwardlytapered vertical shank, an enlargement at the lower end of the shank and adapted to be spaced from the underside of a shoe body, said enlargement having an underside flat and unobstructed and disposed throughout its area at right angles to the verticalcenter of the shank, and a por' tion, of concavo-convex form in cross-section, depending from the said enlargement I and inclined from the vertical. I

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. FREDERICK SCHMIDT.
